UNITED STATES PATENT OFFICE.

WILLIAM V. FOLEY. OF'NEVV BRUNSWICK. NEW JERSEYJASSIGNOR TO INDIA RUBBER COMPANY, A CORPORATION OF NEW JERSEY.

Application filed September 16. 1919.

To all icizom it may com-cm Be it known that I. \Vumuu V. Fou-zv. a citizen of the United States. residing at Xew Brunswick. county of Middlesex, and State of New Jersey. have invented certain new and useful Improvements in Dye Sticks, of which the following is a full. clear. and exact description.

This invention relates to a new and improved dyestick for use in dyeing yarn. cloth or other material.

In the operation of dyeing yarn a stick is inserted through a number of banks of yarn and the stick then supported by its ends upon the sides of the tank containing the dye. with the lower ends of the banks immersed in the dye. At intervals the sticks are lifted and the hanks reversed so that they may be suspended by the ends previously immersed in the dye. The sticks in general use for this purpose have been made of hard wood and it has been found that no matter how smooth a finish has been given to the sticks in manufacture they are prone to splinter and become rough under the action of the heat. moisture and chemicals used in the dye-vat. This is very objectionable. as when the hanks are reversed upon the stick the yarn tends to become caught upon the splinters and tea and this also occurs when the hanks are being slid off or on the sticks. Sticks made of bamboo have been proposed as substitutes. but it hasbeen found that even these become rough and unsuitable after use for a short time.

An object of my invention is to provide a dye stick having a smooth surface which will not be affected by the heat. moisture or chemicals when in use. and which will retain its smooth surface indefinitely.

A further object of my invention is to provide a dye stick having resilient ends which will prevent injury of the ends of the stick when accidentally dropped endwise. as frequently happens in use.

In the drawings:

Figure 1 is a side elevation partly in section of my improved dye stick.

Fig. 2 is a fragmentary section showing a slight modification.

Referring to the drawings the numeral 1 indicates a thin tube of metal. and 2 a thin smooth surfaced tube of hard rubber surrounding and in intimate contact with the DYE-STICK.

tube 1. The hard rubber tube 2 may be lapped over the ends of the metal tube 1 as shown 1n llg. l at or it may terminate sential feature being to provide the surface of the rod with a smooth coating which will not be affected by heat. moisture or the dyes while in use. While it is not essential that the ends of the tube be closed it is preferable to provide plugs as shown. and by making them of a resilient material such as soft rubber. injury to the tube is avoided when the tube is accidentally dropped endwise. hilev l have disclosed the outer coating or tube 2 as made of hard rubber it is obvious that any other suitable material which will function as desired may he used. The substance selccted may be applied to the tube 1 in any suitable way. and l have found that good results are obtained in the case of hard rubber by fitting a tube of the same over the tube 1 and shrinking it thereon. or the hard rubber compound before vulcanization.may be applied to the base and then vulcanized. and any well-known or preferred means may be employed when desired to insure a close bond between the rubber and base. Furthermore the ends 4 may be secured to the stick after they have been vulcanized or may be applied in an unvulcanized state and then vulcanized. due precautions being taken that the right degree of vulcanization be imparted to both the soft ends and the hard cover.

In some cases the yarn or other material is suspended from the sticks. the latter hung in racks and the entire rack immersed in the liquid. thereby obviating reversal of the material on the sticks. case splintering of the stick causes damage when hanging or removing the material. which is prevented by the use of my improved stick.

However. even in this Having thus described my invention. what I claim as new and desire to protect by Letters Patent is:

1. A dye stick comprising a portable rod adapted to rest upon the walls of a dye vat and having a smooth surface coating composed of a material unafiected by the heat, moisture and chemicals to which it is exposed.

2. A dye stick iromprising a portable rod adapted to rest upon the walls of a dye vat and having a hard, smooth coating of a moisture and dye resisting material, the ends of the rod being provided with shock absorbing elements. a

3. A dye stick comprising a thin metallic tube surrounded by a thin closely adhering smooth surfaced tube of hard rubber.

4. A dye stick comprisinga tubular rod having a surrounding smooth surfaced coat of hard rubber lapped over its ends.

5. A dye stick oomprising a tubularrod having a smooth coating of a moisture and dye resisting material, and resilient plugs inserted in the ends of the tube.

6. A dye stick comprising a thin metallic tube surrounded by a thin smooth surfaced tube of hard rubber, and p111 of'soft rubber fitted into the ends of sait metallic tube and having rounded exterior surfaces continuous with the exterior surface of the hard rubber tube.

Signed at New Brunswick,-county of Middlesex. and State of New Jersey, this fourth day of September, 1919.
